The memo mentions Bin Laden planning to hijack planes in the United States. I think that was enough information to keep the CIA, FAA and the Immigration Department with their eyes wide opened. I also doubt that these agencies require some sort of pre authorization from the President to do their jobs as they were suppost to. For example, how they allowed one of the hijackers who had previous trouble with the Immigration back in this country beats the hell out of me. And again, this is not something you call the National Security about. I think most government workers/public servants, don't give a rat about their jobs. They just want a paycheck , job security and early retirement. All they really care about is some dumb annual evaluation given by an immediate supervisor who they're usually good friends with. People tend to ignore things such as possibilities of disasters because it takes them too far from their routine. It's a complicated concept to grasp. Take for instance the subject of AIDS. Most people don't believe they're at risk. Another example, on 9/11, while the towers were burning. Nobody thought those buildings would fall. Nobody thought America could be so vulnerable, and yet we were and still are.
